[PATCH 08/14] dt-bindings: dma: dma350: Document interrupt-names

[Jisheng Zhang <jszhang@kernel.org>]

Currently, the dma350 driver assumes all channels are available to
linux, this may not be true on some platforms, so it's possible no
irq(s) for the unavailable channel(s). What's more, the available
channels may not be continuous. To handle this case, we'd better
get the irq of each channel by name.
